Problems solved by technology

[0002] Wooden furniture is made of solid wood as the main material. With the continuous expansion of the solid wood furniture market in my country, the demand for panels is also large. Wooden furniture usually lasts for a long time. In addition to the hardness and crack resistance of the panels themselves, There are also high requirements for its anti-mold and anti-corrosion performance, but the existing anti-mold technology usually attaches it to the surface or inside of the wooden board by painting or impregnating various protective agents to modify it, but the wood board’s Loss resistance and stability cannot be effectively solved, and it is easy to cause environmental pollution; physical anti-mildew technologies usually include high-temperature sterilization, dipping and smoking methods, etc. The dipping method soaks wooden boards in clean water for about 1 month , to dissolve soluble sugar and some nutrients, the treatment cycle is long, but the anti-mold effect is not ideal, therefore, on the basis of the existing technology, an environmentally friendly method with better anti-mold effect should be studied

Embodiment 1

[0012] A mildew-proof processing method for wooden boards. Wooden raw materials are processed into wooden boards of corresponding thickness. After drying until the water content is 30-35%, they are placed on a support frame. The support frame ensures that the two wooden boards The cut surface is not in contact with the support frame or other wooden boards, then put the support frame into a sealable container, and pass in hot steam until the pressure in the container reaches 230kPa, stop the flow of hot steam, keep it for 5 minutes, and then discharge the steam , until the pressure in the container reaches 128kPa, drain water and continue to discharge steam at the same time; when the pressure in the container is 18kPa, stop draining and exhausting at the same time, and then use a vacuum pump to evacuate the container, when the pressure in the container is -30kPa, stop Evacuate and keep it for 6 minutes. After the completion, the pressure of the container can be restored to norma...

Embodiment 3

[0021] A mildew-proof processing method for wooden boards. Wooden raw materials are processed into wooden boards of corresponding thickness. After drying until the water content is 30-35%, they are placed on a support frame. The support frame ensures that the two wooden boards The cut surface is not in contact with the support frame or other wooden boards, then put the support frame into a sealable container, and pass in hot steam until the pressure in the container reaches 240kPa, stop the flow of hot steam, keep it for 5 minutes, and then discharge the steam , until the pressure in the container reaches 125kPa, drain water and continue to discharge steam; when the pressure in the container is 15kPa, stop draining and exhausting at the same time, and then use a vacuum pump to evacuate the container, when the pressure in the container is -30kPa, stop Evacuate and keep it for 5 minutes.

Abstract

The invention belongs to the technical field of processing of wood slabs, and particularly relates to a mildew-proof processing method of wood slabs. The method comprises the following steps: processing wood raw materials into the wood slabs with corresponding thicknesses; drying to ensure that the moisture is 30 to 35 percent; putting the wood slabs on a support frame; then putting the support frame into a sealed container to carry out treatment under a high-temperature high-pressure condition; then carrying out treatment by utilizing a vacuum condition. Compared with the prior art, the invention has the following advantages that the wood slabs are treated for a period of time under the high-temperature high-pressure condition, vacuum treatment is further carried out, moisture and oil grease inside the wood slabs are separated out, and proteins, starch and a structure of fibers are changed; moreover, mildew inhibitor is applied to the surface of the wood slabs, so that the stability of the wood slabs is greatly improved, the mildew-proof effect is good, the time is long, and the wood slabs are easily popularized and used.
